Description

Technical Field

[0001] This application relates to the field of gas stove technology, such as an energy-concentrating ring component and a gas stove. Background Technology

[0002] Currently, during the use of gas stoves, the heat flow in a household gas stove, i.e., the heat released by the combustion chemical reaction, is the total energy input of the system. Its output mainly consists of three aspects: heat absorption by the pot, radiant heat loss from the high-temperature flame to the outside, and residual heat carried away by the exhaust gas. The radiant heat loss from the high-temperature flame to the outside and the residual heat carried away by the exhaust gas are both losses and represent a waste of gas.

[0003] In related technologies, the energy-concentrating ring of a gas stove uses a single-layer metal sheet to separate the high-temperature flame and flue gas from the secondary air channel at the bottom. Simultaneously, the energy-concentrating shroud has a concave structure to increase the residence time of the high-temperature flue gas, allowing it to undergo secondary combustion and heat exchange inside the shroud. Furthermore, the concave surface of the shroud, when heated, can also radiate heat to the bottom of the pot. Alternatively, the energy-concentrating shroud can have a double-layer structure, theoretically utilizing the air between the two layers to reduce heat transfer between the upper and lower layers.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] In related technologies, the energy-concentrating ring has a foot underneath to support it. The heat from the energy-concentrating ring is easily transferred to the foot, which then transfers the heat to the drip tray or the stovetop below. This can cause heat loss from the gas stove and reduce its thermal efficiency.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0008] This disclosure provides an energy-concentrating ring assembly and a gas stove to reduce the heat transferred downward by the energy-concentrating ring and improve the thermal efficiency of the gas stove.

[0009] This disclosure provides an energy-concentrating ring assembly, which includes: an energy-concentrating ring; a stud, one end of which is connected to the energy-concentrating ring; and a base located below the energy-concentrating ring, the base having a first screw hole that can be connected to the stud to achieve the connection between the energy-concentrating ring and the stud; wherein, a gap exists between the other end of the stud and the base.

[0010] Optionally, the outer wall surface of the stud is provided with a limiting part, and the inner wall surface of the first screw hole is provided with a limiting mating part.

[0012] Optionally, the outer wall of the stud is recessed to form the limiting groove, and the inner wall of the first screw hole protrudes outward to form a limiting protrusion. When the stud is located in the first screw hole, the limiting protrusion abuts against the limiting groove to reduce the contact area between the stud and the first screw hole; and / or, there are multiple limiting protrusions, which are arranged sequentially at intervals along the circumference of the first screw hole.

[0013] Optionally, the first screw hole extends vertically through the base, the stud has a second screw hole, and the energy-concentrating ring assembly further includes a screw that can pass through the first screw hole and extend into the second screw hole to achieve the connection between the base and the stud.

[0046] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0047] Combination Figures 1 to 15 As shown, this embodiment of the present disclosure provides a gas stove, which includes a burner 70 and an energy-concentrating ring 30. The energy-concentrating ring 30 is sleeved on the outside of the burner 70. The burner 70 is used to generate a high-temperature flame to heat the pot above the gas stove. The surface of the energy-concentrating ring 30 can partially absorb the radiant heat from the high-temperature flue gas to the outside. The heated high-temperature energy-concentrating ring 30 then transfers heat to the bottom of the pot through radiative heat exchange, ultimately improving the thermal efficiency of the gas stove. The internal and external directions in this application are as follows... Figure 8 As shown.

[0048] like Figure 2 As shown, this embodiment of the present disclosure provides a pot support assembly, which includes a pot support 10 and an infrared heating device 20. The pot support 10 is used to support the pot. The infrared heating device 20 is disposed above the pot support 10 and is used to absorb the heat of the high-temperature flame and generate infrared radiation to heat the pot.

[0049] In this embodiment, the pot support 10 is generally positioned above the energy-concentrating ring 30. The pot support 10 supports the pot, creating a gap between the pot and the burner 70 to facilitate flame combustion. An infrared heating device 20 is positioned above the pot support 10. When the burner 70 is burning, the infrared heating device 20 absorbs the heat from the high-temperature flame and then radiates the heat to the bottom of the pot, fully utilizing the radiant heat generated by the high-temperature flame. Furthermore, since the infrared heating device 20 is located above the pot support 10, the high-temperature flue gas emitted from the flame will first collide with the infrared heating device 20. During the collision, the flow rate of the high-temperature flue gas slows down, increasing the residence time of the high-temperature flue gas within the infrared heating device 20, allowing for secondary combustion and improving the reuse of the heat from the high-temperature flue gas.

[0050] Optionally, the infrared heating device 20 is fixedly connected to the pot support 10, or the infrared heating device 20 is detachably connected to the pot support 10.

[0051] In this embodiment, the infrared heating device 20 can be fixedly connected to the pot support 10, which increases the connection stability of the infrared heating device 20 and prevents it from falling off. Alternatively, the infrared heating device 20 can be detachably connected to the pot support 10, facilitating disassembly for cleaning, maintenance, and replacement.

[0052] Optionally, when the infrared heating device 20 is fixedly connected to the pot support 10, it can be connected by welding, integration, or other methods to facilitate mass production of the pot support assembly. When the infrared heating device 20 and the pot support 10 are detachably connected, they can be connected by screws, clips, or other methods. For example, the infrared heating device 20 has a first screw hole, and the pot support has a second screw hole; fasteners pass through the first and second screw holes to achieve a detachable connection between the infrared heating device 20 and the pot support 10.

[0053] Optionally, such as Figure 2 As shown, the pot support 10 includes a pot ring 101 and a claw 102. The infrared heating device 20 is connected to the pot ring 101. The claw 102 protrudes above the pot ring 101 and is used to support the pot. The lower end of the claw 102 protrudes from the lower surface of the pot ring 101, and the lower end of the claw 102 is provided with a connecting part, which is suitable for connecting with external components.

[0054] In this embodiment, the support claw 102 of the pot support 10 protrudes from the upper surface of the pot ring 101, allowing the pot support 10 to support the pot and create a gap between the pot and the burner 70. The pot ring 101 is used to fix the support claw 102 and can also be connected to the infrared heating device 20 to fix and connect the infrared heating device 20. The lower end of the support claw 102 has a connecting part, which allows the pot support 10 to connect with external components, such as the energy-concentrating ring 30 or a stove, thus connecting the energy-concentrating ring to the pot support. In this embodiment, the connection method between the infrared heating device 20 and the pot support is applicable to the connection method between the pot ring and the infrared heating device, and will not be described further here.

[0055] It should be noted that the pot support 10 of this application includes not only the support with the pot ring 101, but also the energy-concentrating ring 30 with the claw 102. In other words, any cover capable of supporting the pot is an optional embodiment of this application. For example, when there is no pot ring 101, the infrared heating device 20 can also be connected to the uppermost energy-concentrating ring 30 with the claw 102, which can also achieve the technical effect of this application.

[0056] Optionally, the infrared heating device 20 can be an infrared heating wire, an infrared heating element, etc.

[0057] When the infrared heating device 20 is an infrared heating element, the energy focusing and radiation effects are stronger, and it is easy to clean.

[0058] When the infrared heating device 20 is an infrared heating wire, the infrared heating wire can be a single-layer heating wire, or it can be a wire such as... Figure 8 and Figure 9 The double-layer winding is shown. Optionally, the infrared heating wire can be fixed to the pot support 10 by welding, enabling mass production of the pot support 10 and solving the problem that double-layer winding cannot be mass-produced.

[0059] like Figure 1 As shown in the figure, this embodiment of the present disclosure also provides an energy-concentrating ring assembly, which includes an energy-concentrating ring 30 located below the pot support 10. The energy-concentrating ring 30 facilitates the support of the pot support 10. On the other hand, the energy-concentrating ring can concentrate energy, so that the gas stove has both infrared radiation and energy-concentrating functions, improving the thermal efficiency and user experience of the gas stove.

[0060] Optionally, such as Figure 9 As shown, when the lower end of the claw 102 is provided with a connecting part, the upper surface of the energy-concentrating ring 30 is provided with a connecting mating part that cooperates with the connecting part, and the connecting part and the connecting mating part are detachably connected.

[0061] In this embodiment, the upper surface of the energy-concentrating ring 30 is provided with a connecting mating part, so that the connecting mating part can be detachably connected with the connecting part, thereby realizing the detachable connection between the energy-concentrating ring 30 and the pot support 10. This facilitates the disassembly, cleaning, maintenance and replacement of the pot support 10 and the energy-concentrating ring 30.

[0062] Optionally, one of the connecting part and the connecting mating part includes a positioning protrusion 1021, and the other of the connecting part and the connecting mating part includes a positioning hole 3011. When the positioning protrusion 1021 is located in the positioning hole 3011, the pot support 10 is connected to the energy-concentrating ring 30.

[0063] In this embodiment, the positioning protrusion 1021 and the positioning hole 3011 enable the detachable connection between the pot support and the energy-concentrating ring. The structure is simple, easy to process, and convenient for users to install and disassemble.

[0064] Alternatively, the connecting part and the connecting mating part can also be fixedly connected so that the pot support 10 and the energy-concentrating ring 30 can be fixedly connected. For example, the connecting part and the connecting part can be fixedly connected by welding, gluing or other methods.

[0065] Optionally, there are multiple support claws 102, which are arranged sequentially and spaced apart along the circumference of the pot ring 101 to improve the balance of the pot.

[0066] Optionally, the number of connecting parts is the same as the number of claws 102 and they correspond one-to-one, which can increase the connection stability between the pot support 10 and the energy-concentrating ring 30.

[0067] Optionally, such as Figure 3 As shown, the upper surface of the energy-concentrating ring 30 is constructed with a plurality of protrusions 3012, which are arranged sequentially at intervals along the circumference of the energy-concentrating ring 30; wherein, when the pot support 10 is located above the energy-concentrating ring 30, the lower surface of the pot support 10 abuts against the protrusions 3012 to reduce the contact area between the pot support 10 and the energy-concentrating ring 30.

[0068] In this embodiment, the protrusions 3012 prevent the pot support 10 from coming into surface-to-surface contact with the upper surface of the energy-concentrating ring 30, thereby reducing the heat transferred from the pot support 10 to the lower energy-concentrating ring 30. The arrangement of multiple protrusions 3012 ensures that the pot support 10 is subjected to balanced forces, so that the pot support 10 can be placed stably.

[0069] Optionally, the positioning hole 3011 is provided on the protrusion 3012 to reduce the connection distance between the claw and the energy-concentrating ring, and to reduce the contact area between the claw and the energy-concentrating ring.

[0070] Optionally, such as Figure 3As shown, the number of protrusions 3012 is greater than the number of positioning holes 3011, and the protrusions 3012 with positioning holes 3011 and the protrusions 3012 without positioning holes 3011 are spaced apart. This can ensure the connection stability between the pot support and the energy-concentrating ring, and further reduce the contact area between the pot support and the energy-concentrating ring.

[0071] Optionally, such as Figure 3 As shown, the energy-concentrating ring 30 includes a first cover 301, which is located at the top of the energy-concentrating ring 30. The first cover 301 includes a first wall segment 3013, a second wall segment 3014, and a third wall segment 3015. The first wall segment 3013 extends at least partially in the horizontal direction; the second wall segment 3014...

[0072] The inner end of the second wall segment 3014 is connected to the outer end of the first wall segment 3013; the inner end of the third wall segment 3015 is connected to the outer end of the second wall segment 3014, and the inner end of the third wall segment 3015 is higher than the outer end of the first wall segment 3013; wherein, the upper wall surface of the third wall segment 3015 is constructed with a protrusion 3012.

[0073] In this embodiment, the first cover 301 is located at the top of the energy-concentrating ring 30. It can be understood that when the energy-concentrating ring 30 is a single-piece structure, the first cover 301 is the energy-concentrating ring 30 itself. When the energy-concentrating ring 30 is a multi-layered energy-concentrating ring, the first cover 301 is the uppermost cover of the multi-layered energy-concentrating ring. The upper surface of the energy-concentrating ring 30 refers to the upper surface of the first cover 301. For example, the upper surface of the first cover 301 has a connecting and mating part, and the upper surface of the first cover 301 has a protrusion 3012.

[0074] The inner end of the third wall section 3015 is higher than the outer end of the first wall section 3013. This means that the third wall section 3015, the second wall section 3014, and the first wall section 3013 can form a first step. This first step can block the outward flow of high-temperature flue gas, increase the residence time of the high-temperature flue gas, reduce the heat carried away by the residual heat of the flue gas, and facilitate the reuse of the high-temperature flue gas, thereby improving thermal efficiency. The protrusion 3012 is located on the upper surface of the third wall section 3015, which reduces the contact area between the upper surface of the energy-concentrating ring 30 and the boiler support 10, thus reducing the heat transferred downwards by the boiler support 10.

[0075] Optionally, the second wall segment 3014 slopes upward in a direction from the inside out.

[0076] In this embodiment, the second wall section 3014 is inclined to allow the high-temperature flue gas to flow smoothly, increase the residence time of the flue gas, and at the same time avoid the formation of flue gas entrainment.

[0077] Optionally, such as Figure 9As shown, the second wall segment 3014 has a first angle with the horizontal direction, and the range of the first angle α is 40°≤a≤60°.

[0078] In this embodiment, when the first included angle is less than 40°, the height of the first step is too small, so the first step cannot effectively block the outward flow of high-temperature flue gas. When the first included angle is greater than 60°, the height of the first step is too high, and the high-temperature flue gas is easily entrained, affecting thermal efficiency.

[0079] For example, the first included angle can be 40°, 45°, 50°, 60°, etc.

[0080] Optionally, the burner 70 includes a flame cap with flame holes that are inclined upwards from the inside out. The angle between the flame holes and the horizontal direction is a second angle, which is the same as or similar to the first angle. This allows the high-temperature flue gas generated by the flame at the flame cap to be blocked by the second wall section 3014 when it reaches it. The gas then flows along the second wall section 3014 to the rear part at the top and circulates inwards, increasing the residence time of the flue gas and enabling secondary utilization of the heat from the high-temperature flue gas. This significantly improves thermal efficiency. It also reduces the formation of entrainment in the high-temperature flue gas, further enhancing thermal efficiency.

[0081] Optionally, the energy-concentrating ring 30 is a multi-layer energy-concentrating ring. Specifically, the energy-concentrating ring 30 includes multiple covers, which are spaced apart vertically to form a multi-layer energy-concentrating ring. The multiple covers are spaced apart vertically to form multiple cavities arranged vertically within the energy-concentrating ring 30.

[0082] In this embodiment, the energy-concentrating ring 30 is a multi-layer energy-concentrating ring. The multiple cavities formed by the multi-layer energy-concentrating ring can isolate the heat transmitted downward by the pot support 10, and the multi-layer energy-concentrating ring isolates the heat flow generated by gas combustion from the outside air, reducing heat exchange with the outside air, thereby further improving the thermal efficiency of the gas stove.

[0083] Optionally, such as Figure 3 , Figure 5 and Figure 6As shown, the outer edge of the first cover 301 is provided with a first through hole 3016; the energy-concentrating ring 30 also includes a second cover 302, which is located below the first cover 301. The second cover 302 and the second cover 302 enclose a heat insulation cavity. The outer edge of the second cover 302 is provided with a first folded edge protrusion 3021, which constructs a first folded edge 3022 and a second folded edge 3023, and the first folded edge 3022 is higher than the second folded edge 3023. When the first cover 301 and the second cover 302 are assembled, the first folded edge 3022 is located in the first through hole 3016 to achieve the positioning of the first cover 301 and the second cover 302. The second folded edge 3023 abuts against the lower surface of the first cover 301 to support the first cover 301.

[0084] In this embodiment, the first cover 301 and the second cover 302 enclose each other to form a heat-insulating cavity, which reduces the heat transferred from the first cover 301 to the second cover 302. The first folded protrusion 3021 includes a first folded edge 3022 and a second folded edge 3023. The first folded edge 3022 is higher than the second folded edge 3023, so that the first folded edge 3022 can extend into the first through hole 3016, playing a positioning role for the first cover 301 and the second cover 302, thereby facilitating the assembly of the first cover 301 and the second cover 302. At the same time, the second folded edge 3023 can abut against the lower surface of the first cover 301, thus reducing the contact area between the first cover 301 and the second cover 302, achieving point contact between the first cover 301 and the second cover 302, thereby reducing the heat transferred from the first cover 301 to the second cover 302, reducing the heat loss of the gas stove, and improving the thermal efficiency of the gas stove.

[0085] In this embodiment, the first folded edge 3022 and the second folded edge 3023 are an integral structure. The height difference between the first folded edge 3022 and the second folded edge 3023 simultaneously positions the first cover 301 and provides support contact between the first cover 301 and the second cover 302. This facilitates installation and reduces the contact area between the first cover 301 and the second cover 302, thereby reducing the heat transferred downward from the first cover 301. For example, the first side 3022 has two second folded edges 3023 at both ends to improve the support balance and stability of the first folded edge protrusion 3021 for the second cover 302.

[0086] Optionally, there may be multiple first folded edge protrusions 3021, and the multiple first folded edge protrusions 3021 are arranged sequentially at intervals along the circumference of the second cover 302.

[0087] In this embodiment, multiple first folded edge protrusions 3021 are arranged sequentially at intervals along the circumference of the second cover 302, thereby increasing the balanced force between the first cover 301 and the second cover 302 and improving the placement stability of the first cover 301.

[0088] For example, the number of first folded edge protrusions 3021 is four to improve the balance of forces.

[0089] Optionally, such as Figure 5 As shown, the energy-concentrating ring 30 also includes a third cover 303, which is located between the first cover 301 and the second cover 302. The outer edge of the third cover 303 is provided with a second through hole 3031. The outer edge of the second cover 302 is also provided with a second folded edge protrusion 3024, which is constructed with a third folded edge 3025 and a fourth folded edge 3026. The third folded edge 3025 is higher than the fourth folded edge 3026. When the third cover 303 is assembled with the second cover 302, the third folded edge 3025 is located in the second through hole 3031 to achieve positioning of the third cover 303 and the second cover 302. The fourth folded edge 3026 abuts against the lower surface of the third cover 303 to support the third cover 303. The second folded edge protrusion 3024 is higher than the first folded edge protrusion 3021, and the third cover 303 is provided with a third through hole 3032 so that the second folded edge protrusion 3024 passes through the third through hole 3032 and cooperates with the first cover 301.

[0090] In this embodiment, as Figure 4 , Figure 6 and Figure 7As shown, the energy-concentrating ring 30 includes a third cover 303, which is located between the first cover 301 and the second cover 302. The third cover 303 divides the heat-insulating cavity into a first cavity and a second cavity. Specifically, the first cover 301 and the third cover 303 enclose the first cavity, and the third cover 303 and the second cover 302 enclose the second cavity, with the first cavity located above the second cavity. The second cover 302 also has a second folded protrusion 3024. The third fold 3025 of the second folded protrusion 3024 positions the second cover 302, and the fourth fold 3026 allows the second cover 302 to be supported below the third cover 303. This point contact between the second cover 302 and the third cover 303 reduces heat transfer between them, further reducing the downward transfer of heat from the third cover 303. The first folded protrusion 3021 passes through the third through hole 3032, through the third cover 303, and abuts against the first cover 301. This allows point contact between the first cover 301, the second cover 302, and the third cover 303, reducing the contact area between the three covers. This not only insulates the first and second cavities, reducing the heat transferred downwards between the pot support 10 and the first cover 301, but also reduces the contact area between the first cover 301, the second cover 302, and the third cover 303, further reducing heat transfer from the upper layer to the lower layer. Furthermore, the first cover 301 isolates the heat from the pot support 10 above the first cover 301, reducing the heat transferred downwards from the first cover 301, further reducing heat loss from the gas stove and improving its thermal efficiency.

[0091] Optionally, there may be multiple second folded edge protrusions 3024, which are arranged sequentially at intervals along the circumference of the second cover 302.

[0092] In this embodiment, the arrangement of multiple second folded edges 3023 can increase the force balance between the second cover 302 and the third cover 303, and improve the stability of the third cover 303.

[0093] Optionally, a plurality of second folded edge protrusions 3024 and a plurality of first folded edge protrusions 3021 are arranged sequentially at intervals along the circumference of the second cover 302.

[0094] In this embodiment, the second cover 302 is provided with a first folded edge protrusion 3021 and a second folded edge protrusion 3024. The multiple first folded edge protrusions 3021 and second folded edge protrusions 3024 are arranged at intervals, so that the forces between the second cover 302 and the third cover 303, and between the second cover 302 and the first cover 301 can be more balanced, so that all three covers can be placed stably.

[0095] Optionally, the second cover 302 includes a first horizontal section and a first vertical section. The first vertical section is connected to the outer end of the first horizontal section and extends upward. The first folded edge protrusion 3021 and the second folded edge protrusion 3024 are disposed above the first vertical section to reduce the distance between the first folded edge protrusion 3021 and the second folded edge protrusion 3024 and the first cover 301 and the third cover 303, so as to facilitate the assembly of multiple covers.

[0096] Optionally, the third cover 303 includes a second horizontal section and a second vertical section. The second vertical section is connected to the outer end of the second horizontal section and extends upward. The second through hole 3031 is located above the second vertical section to reduce the mating distance between the second through hole 3031 and the second folded protrusion 3024 and improve assembly convenience.

[0097] Optionally, such as Figure 9 As shown, the outer edge of the first cover 301 is bent downward to form a rolled edge 3017, and the upper wall surface of the rolled edge 3017 is constructed with a first through hole 3016.

[0098] In this embodiment, the outer edge of the first cover 301 is bent downward to form a rolled edge 3017, and the first through hole 3016 is provided on the upper surface of the rolled edge 3017. This can appropriately reduce the height of the first folded edge protrusion 3021, allowing the first cover 301 to be assembled with the second cover 302 or the third cover 303 at the shortest distance, improving the convenience of assembly. Moreover, providing the first through hole 3016 at the outer edge can ensure the radial dimension of the heat insulation cavity, increase the volume of the heat insulation cavity, and improve the heat insulation effect.

[0099] Optionally, the second through hole 3031 is provided at the outer edge of the third cover 303 to facilitate the assembly of the third cover 303 and the second cover 302.

[0100] Optionally, the first folded edge protrusion 3021 and / or the second folded edge protrusion 3024 are provided at the edge of the second cover 302 to facilitate the assembly between the second cover 302 and the first cover 301 and the second cover 302.

[0101] Optionally, the first cover 301, the third cover 303 and the second cover 302 are arranged at intervals from top to bottom, and the rolled edge 3017 is located outside the second cover 302 and the third cover 303, and the lower end of the rolled edge 3017 extends to the lower part of the outer end of the second cover 302.

[0102] In this embodiment, the rolled edge 3017 extends all the way to the bottom of the second cover 302, so that the rolled edge 3017 can cover the gap between the first cover 301 and the third cover 303 and the gap between the third cover 303 and the second cover 302, preventing dust and oil from entering the cavity of the energy-concentrating ring 30 through the gap, so as to facilitate the cleaning and maintenance of the energy-concentrating ring 30.

[0103] Optionally, the rolled edge 3017 is connected to the outer end of the third wall segment 3015, and the upper wall surface of the rolled edge 3017 is higher than the upper wall surface of the third wall segment 3015.

[0104] In this embodiment, the rolled edge 3017 is higher than the third wall section 3015, so that the rolled edge 3017 can further block the high-temperature flue gas and prevent the high-temperature flue gas from flowing outward.

[0105] Optionally, such as Figures 11 to 15 As shown, the gas stove also includes a stud 50 and a foot 60. One end of the stud 50 is connected to the energy-concentrating ring 30. The foot 60 is located below the energy-concentrating ring 30 and has a first screw hole 601. The first screw hole 601 can be connected to the stud 50 to realize the connection between the energy-concentrating ring 30 and the stud 50. There is a gap between the other end of the stud 50 and the foot 60.

[0106] In this embodiment, the energy-concentrating ring 30 and the base 60 are connected by a stud 50 and a first screw hole 601. The heat of the energy-concentrating ring is transferred to the stud and then to the base. The stud provides intermittent heat transfer, which reduces the amount of heat transferred downwards by the energy-concentrating ring. A gap exists between the other end of the stud 50 and the base 60, reducing the contact area between them and further insulating the heat. This reduces the amount of heat transferred from the energy-concentrating ring 30 to the base 60. The base 60 contacts the gas stove's liquid collection tray. This structure reduces heat loss to the gas stove surface and improves thermal efficiency.

[0107] It should be noted that: the other end of the stud 50 has a gap with the base 60, which can mean that the other end of the stud 50 does not contact the base 60, or that the other end of the stud 50 partially contacts the base 60. Any method that can reduce the contact area between the base and the stud is an optional embodiment of this application.

[0108] Optionally, the outer wall surface of the stud 50 is provided with a limiting part, and the inner wall surface of the first screw hole 601 is provided with a limiting mating part. When the limiting part and the limiting mating part are engaged, the stud 50 and the first screw hole 601 are restricted from rotating.

[0109] In this embodiment, the structure of the limiting part and the limiting mating part can prevent the energy-concentrating ring 30 from rotating when the energy-concentrating ring 30 and the base 60 are assembled, thereby improving the convenience of gas stove installation and use.

[0110] Optionally, such as Figure 12 and Figure 13 As shown, one of the limiting part and the limiting mating part includes a limiting groove 501, and the other of the limiting part and the limiting mating part includes a limiting protrusion 602. When the stud 50 is located in the first screw hole 601, the limiting protrusion 602 is located in the limiting groove 501 to restrict the stud 50 from rotating relative to the first screw hole 601.

[0111] In this embodiment, the limiting protrusion 602 and the limiting groove 501 are easy to process and operate, making it convenient for users to assemble and disassemble the gas stove. Moreover, the limiting protrusion 602 and the limiting groove 501 have a significant limiting effect and a high cost-performance ratio.

[0112] Optionally, there may be multiple limiting protrusions 602, which are arranged sequentially at intervals along the circumference of the first screw hole 601.

[0113] In this embodiment, multiple limiting protrusions 602 are arranged sequentially at intervals along the circumference of the first screw hole 601, which can increase the limiting of the stud 50 and the first screw hole 601 in the circumferential direction.

[0114] Optionally, the outer wall of the stud 50 is recessed to form a limiting groove 501, and the inner wall of the first screw hole 601 protrudes outward 3012 to form a limiting protrusion 602. When the stud 50 is located in the first screw hole 601, the limiting protrusion 602 abuts against the limiting groove 501 to reduce the contact area between the stud 50 and the first screw hole 601.

[0115] In this embodiment, when the stud 50 and the first threaded hole 601 are assembled, the lower end face of the stud 50 does not contact the base 60. The circumferential direction of the stud 50 makes point contact with the inner wall surface of the first threaded hole 601 through the limiting protrusion 602 and the limiting groove 501, further reducing the contact area between the stud 50 and the base 60 and reducing the heat transferred from the stud 50 to the base 60. The limiting protrusion 602 and the limiting groove 501 not only achieve the limiting function, but also reduce the contact area between the stud 50 and the first threaded hole 601.

[0116] Optionally, the limiting protrusion 602 extends along the depth direction of the first screw hole 601, and the limiting groove 501 matches the limiting protrusion 602 to increase the contact area of ​​the limiting protrusion 602 and the limiting groove 501 in the depth direction, thereby ensuring the limiting function.

[0117] Optionally, the first screw hole 601 extends vertically through the foot 60, and the lower end of the stud 50 is provided with a second screw hole 502. The energy-concentrating ring 30 assembly also includes a screw that can pass through the first screw hole 601 and extend into the second screw hole 502 to achieve the connection between the foot 60 and the stud 50.

[0118] In this embodiment, the stud 50 and the first screw hole 601 are connected by screws to increase the connection stability between the stud 50 and the base 60. Moreover, the stud 50 and the first screw hole 601 only contact each other through the limiting protrusion 602 and the limiting groove 501, and are then connected by screws, which minimizes the contact between the stud 50 and the base 60, thereby reducing the heat transferred downward by the energy-concentrating ring 30.

[0119] In addition, the connection method using screws, studs, and feet facilitates the sequential assembly of the gas stove, making it easy for users to disassemble, clean, and install.

[0120] Optionally, such as Figure 14 As shown, the stud 50 has a recess 503 with its opening facing downwards. A second threaded hole 502 is located inside the recess 503, and there is a gap between the second threaded hole 502 and the recess 503. The stud 50 also includes a connecting rib 504, which connects the inner wall surface of the recess 503 and the outer wall surface of the second threaded hole 502.

[0121] In this embodiment, the structure of the concave hole 503 and the second screw hole 502 makes the stud 50 a hollow structure. In this way, the screw contacts the second screw hole 502, and the outer wall surface of the second screw hole 502 does not directly contact the inner wall surface of the concave hole 503. Moreover, the two are connected by a connecting rib 504, which can reduce the heat transferred from the stud 50 to the screw, thereby reducing the heat transferred downward by the screw.

[0122] Optionally, there may be multiple connecting ribs 504, which are arranged sequentially at intervals along the circumference of the second screw hole 502. This ensures connection stability and reduces the contact area between the second screw hole 502 and the recess 503.

[0123] Optionally, the lower wall surface of the second screw hole 502 is higher than the lower wall surface of the recessed hole 503.

[0124] In this embodiment, the lower wall surface of the second screw hole 502 is higher than the lower wall surface of the recessed hole 503, which increases the distance between the lower wall surface of the second screw hole 502 and the base 60, reducing heat transfer between the stud 50 and the base 60.

[0125] In this embodiment, the heat from the pot support 10 decreases layer by layer through the multi-layer energy-concentrating rings, studs 50, and bases 60, so very little heat is transferred to the bases 60. The bases 60 are in contact with the gas stove's liquid tray. This structure reduces the heat loss introduced to the gas stove surface and also improves thermal efficiency.

[0126] Optionally, the second cover 302 is located at the lower part of the energy-concentrating ring 30. The second cover 302 is provided with a limiting hole 3027, and one end of the stud 50 is located in the limiting hole 3027 to realize the connection and limiting of the energy-concentrating ring 30 and the stud 50.

[0127] In this embodiment, one end of the stud 50 extends into the limiting hole 3027 of the second cover 302 to connect the stud 50 and the energy-concentrating ring 30. The limiting hole 3027 also engages with the outer wall surface of the stud 50 to prevent rotation of the stud 50 when it is fixed to the base 60 with screws, thus providing a limiting function.

[0128] For example, such as Figure 5 As shown, the limiting hole 3027 is a square hole, which matches the outer wall surface of the stud 50 to restrict the rotation of the stud 50 relative to the energy-concentrating ring 30.

[0129] The cross-sectional area of ​​one end of the stud 50 is larger than the cross-sectional area of ​​the limiting hole 3027, so that the stud 50 will not fall off the limiting hole 3027, thus realizing the connection between the stud 50 and the second cover 302.

[0130] Optionally, such as Figure 11 As shown, the energy-concentrating ring assembly also includes a bottom shell 40, which is located below the energy-concentrating ring 30 and above the base 60. The bottom shell 40 is provided with a fourth through hole 401. The stud 50 passes through the limiting hole 3027 and the fourth through hole 401 in sequence and is connected to the base 60. The edge of the fourth through hole 401 protrudes upward 3012 to form a convex edge 402, which abuts against the lower surface of the second cover 302.

[0131] In this embodiment, the protruding edge 402 is supported between the lower surfaces of the bottom shell 40 and the second cover 302, which reduces the contact area between the second cover 302 and the bottom shell 40, thereby reducing the heat transferred from the second cover 302 to the bottom shell 40 and reducing the heat transferred downward by the gas stove.

[0132] Optionally, there are multiple fourth through holes 401, which are arranged sequentially at intervals along the circumference of the bottom shell 40. Each fourth through hole 401 is provided with a corresponding protruding edge 402 to ensure that the second cover 302 can be balanced under force and improve the stability of the second cover 302.

[0133] Optionally, the energy-concentrating ring 30 can be a double-layer energy-concentrating ring, a triple-layer energy-concentrating ring, or a four-layer or more energy-concentrating ring.

[0134] Optionally, the gas stove may also include a heat insulation device to reduce heat transfer between components.

[0135] Optionally, a heat insulation device may be provided at the connection between the stud 50 and the second cover 302 to further reduce heat transfer between the second cover 302 and the stud 50.

[0136] For example, the cross-sectional area of ​​one end of the stud 50 is larger than the cross-sectional area of ​​the limiting hole to achieve the connection between the stud 50 and the energy-concentrating ring. The lower surface of one end of the stud 50 abuts against the upper surface of the second cover. Optionally, a heat insulation device can be disposed between the lower surface of one end of the stud 50 and the upper surface of the second cover, thus achieving both heat insulation and adjustment of the height of the energy-concentrating ring.

[0137] Optionally, the foot 60 is located below the base shell 40 to support the base shell 40. A heat insulation device may also be provided between the foot 60 and the base shell 40 to reduce heat transfer between the base shell 40 and the foot 60.

[0138] Optionally, a heat insulation device can also be provided between the upper surface of the protruding edge 402 and the lower surface of the second cover to achieve the functions of heat insulation and height adjustment.

[0139] Optionally, a heat-insulating material can also be provided between the other end of the stud 50 and the base 60 to further reduce heat transfer between the stud 50 and the base 60. Specifically, a heat-insulating pad can be provided between the lower end face of the stud 50 and the base 60. This not only reduces heat transfer between the stud 50 and the base 60 but also increases the connection stability between the stud 50 and the base 60. Moreover, adjusting the height of the heat-insulating pad can adjust the height of the stud 50, and thus the height of the energy-concentrating ring 30.

[0140] Optionally, the energy-concentrating ring assembly also includes a liquid receiving plate 80, which is located below the bottom shell 40, and a foot 60 is located above the liquid receiving plate 80. The foot 60 is provided with a limiting member, and the liquid receiving plate 80 is provided with a limiting mating member. When the limiting member and the limiting mating member are engaged, the liquid receiving plate and the foot 60 can restrict rotation.

[0141] In this embodiment, the drip tray 80 increases the contact area between the gas stove and the cooktop, improving the stability of the gas stove. Furthermore, the drip tray 80 can collect spilled soup or other liquids from the cookware, facilitating cleaning of the gas stove.

[0142] For example, the liquid receiving tray is constructed with a groove, and the outer wall surface of the base 60 matches the groove. When the base 60 is located in the groove, the base 60 and the liquid receiving tray can restrict rotation.

[0143] Optionally, there may be multiple feet 60, which are arranged at intervals along the circumference of the gas stove. The arrangement of multiple feet 60 increases the balance and stability of the gas stove. Optionally, the number of locking slots is the same as the number of feet 60 and corresponds one-to-one, to enhance the limiting function of the locking slots and feet 60.

[0144] This disclosure also provides a gas stove, which includes the energy-concentrating ring assembly described above.

[0145] The gas stove provided in this embodiment includes the energy-concentrating ring assembly described above, and therefore has the beneficial effects of the energy-concentrating ring assembly described above, which will not be repeated here.
